Summary

Fixes four confirmed gaps (org backlog item 33) preventing consumers from operating contextual-orchestrator via the plain, unmodified OpenAI SDK. Every fix is at the server's own request/response shape — no CO-specific client library.

  • Batches: new POST/GET /v1/batches, GET /v1/batches/{id}, POST /v1/batches/{id}/cancel (client.batches.create/retrieve/list/cancel()), wrapping the existing submit_batch/LocalBatchBackend/PgLlmBatchBackend machinery. input_file_id is a file already uploaded through POST /v1/files with purpose=batch; a completed batch's real, already-computed results are reshaped into an OpenAI output-file line format and registered as a downloadable gateway file (FileRegistry.register_local), so client.files.content() works on the output too. Only endpoint: "/v1/chat/completions" is wired — other endpoints fail closed with invalid_endpoint rather than being silently mishandled.
  • Audio transcription: POST /v1/audio/transcriptions now detects multipart/form-data (the SDK's audio.transcriptions.create() always sends multipart, never JSON) the same way /v1/files already does, translating file/model/language/response_format/prompt/temperature form fields into the existing input_audio: {data, format} JSON shape instead of 415ing.
  • Audio-output chat: /v1/chat/completions now accepts modalities: ["text","audio"] + audio: {voice, format} — the only SDK-native way to request spoken-audio chat output — by routing to the same single-agent capability="audio" passthrough /v1/audio/generations already used. /v1/audio/generations is left in place, unremoved.
  • GET /v1/videos (list): left intentionally unimplemented, documented in place — unlike Files/Batches this gateway keeps no locally cached video-job status (retrieve always re-fetches live from the owning provider), so a real list needs per-job provider fan-out, a materially larger and different feature than retrieve/content. This is the lowest-priority item per the gap review's own text, which explicitly allows "confirm and document" as the resolution.

Also fixed ModelClient.proxy_upload's mock transport to return the created_at/status fields the real OpenAI FileObject shape requires — it was silently unusable by a genuine SDK client, which blocked writing an honest test for the existing /v1/files endpoint in the first place.

PR #1012 (chat↔responses shape translation) is a separate, unrelated gap and is not duplicated here.

Test plan

  • tests/test_openai_sdk_compat.py (new): instantiates the real openai package's client (openai.OpenAI(api_key=..., base_url=...)) against a live gateway HTTP server and drives every fixed operation through the stock SDK's own methods — batches create/retrieve/list/cancel round trip (including downloading and parsing the real output file), an unsupported-endpoint 400, an unknown-batch-id 404, a multipart transcription upload (verified via a captured-payload test double), and audio-output chat completions (success + capability-unavailable 503).
  • Fixed two pre-existing tests whose assertions were stale against the new (more permissive, more specific) audio-modalities contract (invalid_modalitiesinvalid_audio when modalities opts into audio output but omits audio).
  • Added a FileRegistry.register_local/is_local/local_content unit test.
  • coverage run -m pytest tests && interrogate — 100% docstring coverage on touched files; bandit -ll clean.
  • Full suite (uv run --extra api --extra db --extra queue --group dev python -m pytest -q) — 3307 tests, all passing after the two stale-test fixes above.

…hable

Four operations the stock OpenAI SDK (api_key + base_url only) could not
reach, all fixed at the server's own request/response shape rather than by
inventing a CO-specific client:

- Add POST/GET /v1/batches and POST /v1/batches/{id}/cancel
  (client.batches.create/retrieve/list/cancel()), wrapping the existing
  submit_batch/LocalBatchBackend/PgLlmBatchBackend machinery. Input comes
  from a file already uploaded through /v1/files with purpose=batch; a
  completed batch's real, already-computed results are reshaped into an
  OpenAI-shaped output file and registered as a downloadable gateway file
  (FileRegistry.register_local) so client.files.content() also works for
  it. Only endpoint=/v1/chat/completions is wired; other endpoints fail
  closed with invalid_endpoint.
- Give POST /v1/audio/transcriptions the same multipart-detection
  treatment /v1/files already had, translating the SDK's always-multipart
  audio.transcriptions.create() upload into the existing input_audio JSON
  shape instead of 415ing.
- Let /v1/chat/completions accept modalities=["text","audio"] +
  audio:{voice,format} -- the only SDK-native way to request audio-output
  chat completions -- by routing to the same single-agent capability="audio"
  passthrough /v1/audio/generations already uses.
- Document (not implement) why GET /v1/videos (list) stays out of scope:
  unlike Files/Batches this gateway keeps no locally cached video-job
  status, so a real list needs per-job provider fan-out, a materially
  different feature than retrieve.

Also fixed the mock file-upload transport (ModelClient.proxy_upload) to
return the created_at/status fields the real OpenAI FileObject shape
requires -- it was silently unusable by a genuine SDK client, which blocked
writing a real test for /v1/files in the first place.

tests/test_openai_sdk_compat.py instantiates the actual openai package's
client against a live gateway server and drives every fixed operation
through the stock SDK's own methods (never hand-rolled JSON), including a
minimal test-double file transport that makes upload/download round-trip
real bytes so the batch flow is exercised end to end.

PR #1012 (chat<->responses shape translation) is a separate gap and is not
duplicated here.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 68bc6

This PR adds public batch lifecycle and downloadable-output handling, but concurrent retrieval, cancellation, and completion can update shared state non-atomically, allowing duplicate output files or overwritten terminal status; input validation also accepts mismatched batch URLs and non-finite temperatures, so fixes or explicit owner acceptance are needed before merge.

6082-6084: 🚀 Performance & Scalability | 🔵 Trivial

목록 응답이 배치 수만큼 폴링을 수행합니다.

_batch_document는 호출마다 coordinator.poll_batch를 실행하고, 필요하면 retrieve_batch와 출력 파일 생성까지 수행합니다. limit의 최대값은 100이므로 한 번의 GET /v1/batches 요청이 최대 100번의 백엔드 폴링과 최대 100번의 출력 실체화를 유발합니다. 각 호출은 _run으로 실행 슬롯을 순차적으로 점유합니다.

목록 경로에서는 추적된 상태만 렌더링하고, 실체화는 단건 조회(GET /v1/batches/{id})에서만 수행하는 방안을 검토하십시오.

로컬 파일 콘텐츠의 보관 정책을 확인하십시오.

local_file_content 매핑은 배치 출력 JSONL 전체를 base64 텍스트로 보관합니다. base64 인코딩은 크기를 약 33% 늘립니다. 이 항목은 delete가 호출될 때만 제거됩니다. 배치를 많이 생성하는 배포에서는 이 매핑이 계속 증가합니다.

Rebased this PR onto current main (it was stuck mergeable_state: behind against a stale base sha 8839081...).

CI status before merge: no genuine failures — most required checks were still queued at the stale head (this PR's checks appear to have been stuck behind the same backlog as the other PRs in this batch); CodeRabbit and Devin Review had both completed successfully.

Merge: git merge origin/main was completely clean, including fuzz/targets.py (untouched by this PR, unlike a couple of the other PRs in this batch that collided there with #917's rater-observation addition). No conflicts.

Verification (Python 3.12 venv, pip install --require-hashes -r requirements.lock + pip install --no-deps -e ., plus pip install "openai>=2.0" for this PR's new dev-only real-SDK compat test):

  • tests/test_openai_sdk_compat.py, test_chat_modalities_http_honesty.py, test_empty_modalities_prediction_noop_http_honesty.py, test_files_api.py (this PR's own/touched suites) — 29 passed
  • Broader sweep of every test touching modalities/audio/batch/file-registry/server/orchestrator (-k "modalities or audio or batch or file_registry or files_api or server or orchestrator", 3361 tests) — 478 passed, 0 failed
  • tests/test_planning_adr_identifiers.py — passed (this PR adds no new ADR)
  • interrogate on the three touched source files (server.py, orchestrator.py, file_registry.py) — 100% docstring coverage
  • Package import sanity — OK

Pushed directly to feat/openai-sdk-batches-audio-modalities (no force-push).

PR #1022의 현재 리뷰 findings를 exact head 39acedeadc98388b4a7bbdf378b609adc3c27f86에서 재검증하고 공통 경계에서 수리했습니다.

  • 최신 protected main@c4f932b0aebe6fb7ba743451fa47775b678a7f8c를 비강제 merge했습니다.
  • Batch JSONL은 각 줄의 endpoint를 요청 endpoint와 일치시키고, 검증된 Chat Completions 옵션을 BatchRequest에서 로컬·pg-llm-batch 실행까지 보존합니다.
  • 취소는 BatchBackend.cancelCostRoutingCoordinator.cancel_batch를 거쳐 backend가 수락한 상태만 노출합니다. 완료가 먼저 이기면 결과와 계량을 보존합니다.
  • transient download 오류는 terminal failure로 저장하지 않습니다. 기존 durable per-job lock으로 polling, retrieval, output 등록, batch 상태 publish를 single-writer로 묶었습니다.
  • unknown usage는 null, input file은 purpose=batch, completion window는 실제 지원하는 24h만 허용합니다.
  • transcription text/srt/vtt는 bounded text transport로 응답하며 temperature는 공용 finite/range validator를 사용합니다.
  • JSONL·multipart 파서는 기존 Hypothesis/Atheris 공용 seam에 추가했습니다.
  • docs/library_research.md에 OpenAI Python v2.11 계약과 기존 batch 연구 근거를 기록했습니다. 새 runtime dependency는 없습니다.

검증:

  • 정확한 CI 명령: uv run --locked --extra api --extra db --extra queue --group dev python -m pytest -q3414 passed, 2 skipped, 경고 없음
  • latest-main merge 후 관련 재검증 → 310 passed, 3106 deselected
  • latest-main security metadata → 11 passed
  • 변경 source docstring coverage → 100.0%
  • focused Ruff fatal/static checks와 git diff --check 통과

force push, self-approve, merge는 하지 않았습니다. 현재 hosted required checks는 새 exact head에서 queued 상태입니다.
